STEAM-RADlATO R.

SPECIFICATION forming part of Letters Patent No. 295,343, dated March18, 1834. Appia-mon met June s, ms. No model.)

To @ZZ whom t may concern.-

Be it known that we, ROBERT BRASS and JOHN CHAPMAN, Aboth of Brooklyn,in the county of Kings and State of New York, have invented certain newand useful Improvements in Steam-Radiators, of which the following is aspecification.

This invention has reference to improvements in that class ofsteam-radiators which are made entirclyfof cast-iron, and in which thesteam enters at the top of the radiator,

while the water of condensation is coilected and and of a bottom chamberhaving an inclined.

bottom, the top and bottom chambers having interior side and centerlugs, to which the flanges of the middle portion are secured byvscrew-bolts.

In the accompanying drawings, Figure 1 represents a verticallongitudinal section on line a: as, Fig. 3, of our improvedsteam-radiator. Fig. 2 is a vertical transverse section of the same online?,l y, Fig. l. Fig. 3 is a horizontal section on linezz, Fig. l;Fig. it, a plan of the bottom chamber, shown as detached; and Fig. 5 isa horizontal section of the top chamber on line c c, Fig. l.

Similar letters of reference indicate corresponding parts.

Ain the drawings represents a cast-iron top chamber, which is providedwith 'longitudinal bottom openings, c a., and at one 'end with asteam-inlet pipe, a. Aperforated ornamental top plate, A', is placed onthe top of the chainber A, so as to prevent contact with the heatedsurface of the same.

B is a bottom chamber, which is also made of cast-iron, and providedwith longitudinal top openings, Zn b, an inclined bottom, 11', and adischarge-pipe, be, for the water of condensation, at the lowermost partof the bottom b. The top chamber, A, is connected with the bottomchamber, B, by one or more intermediate castings, G, each of whichconsists of a row of circulating-pipes, d d, which are made ofstarshaped or other suitable cross-section, so that a largeradiating-surface is obtained. Each row of pipes C is provided at theupper and lower ends with iianges d' d2, respectively, which are castintegral with the body of the circulating-pipesC, so as to serve as adirect means of connection between the top and bottom chambers. Thecontact-faces of the iianges d d'2 of the intermediate casting, C, aswell as the adjoining faces of the top and bottoni chambers, A and B,are planed or smoothly ground oft', whereby they iit exactly to eachother, th ey being furthermore packed by an intermediate layer of leador other suitabie packing, so as to prevent the escape of steam. Thedanges d d2 of the circulating-pipes d d are secured to the face-platesof the top and bottom chambers by screw-bolts (Z3. For this purpose thetop and bottom chambers are provided with interior projecting lugs, e e,cast integral with the chambers at the side walls of the same.Screwholes are drilled through the face-plates of said chambers and intothe lugs c, but not entirely through the same, but of sufficient depth,so that the screw-bolts can firmly take hold of the same. The auges dd2' are perforated for the passage of the fastening-bolts. Then theradiator is to be constructed with more than one row ofcirculating-pipes, the top and bottom chambers are further cast withcenterlugs, e' e', extending transversely between the longitudinalopenings c a and Z1 I) of said chambers. These lugs serve also tostrengthen the faceplates of the chambers A and B, as they have to bemade wider when several rows of circulating-pipes are to be used.Through the lugs c and top and bottom plates of the chambers Aand B aredrilled holes-one at each end ofthe lugs-also corresponding holes in theflanges d di. rlhe top chamber,A, is first connected to the intermediatecastings, C C, by being placed ininverted position. The castings Careplaced thereon, and the screw-bolts e e then dropped, with theirthreadedshanlrs downward, through the holes of the iianges and centerlugs, and then screwed tight by nuts e. The bottom chamber, B, is thenconnected in the same manner with the castings O, which are placed inupright position on the bottom chamber. The screw-bolts of the side lugsare next screwed in, and thus a rigid connection of the main parts ofthe radiator obtained, in which all the screw-bolts engage solidportions of the chain- IOO bers Without giving exit to the steam, sothat leakage resulting from untightness of the parts is entirelyobviated. As the main parts composing the radiator are made ofcast-iron, a radiator of cheap construction that emits the heat quicklyand effectively is obtained.

Having thus described our invention, we claim as new and desire tosecure by Letters Patentl. Asteam-radiator composed of atop chamberhaving bottom openings, an intermediate casting or castings, eachcomposed of a row of circulatingpipes having top and bottom flanges eastintegral therewith, a bottom chamber having openings at the upper part,and means whereby the top and bottom chambers are connected to theflanges of the intermediate casting or castings, substantially as andfor the purpose set forth.

2. The combination, in a steam-radiator, of the top andbottom chambers,A and B, having openings a a and b b, and interior projecting lugs, e e,cast integral with said chambers, an intermediate casting, C, composedof a row of circulating-pipes, d d, and top and bottom flanges, d d2,cast integral therewith, said top and bottom chambers being connected tothe -llanges of the intermediate circulating-pipes by screw-bolts thattake into the interior` lugs of the chambers, substantially as setforth.

3. The combination of top and bottom chambers, A and B, having openingsa a and b b, and interior side and center lugs, e3 e', intermediatecastings, C C, each composed of a row of circulating-pipes, d d, and oftop and bottom flanges, d d2, and screwbolts et and e, that connect theflanges of the castings with the lugs of the top and bottom chambers,substantial] y as set forth.

4. Ina steam-radiator, the combination of the top and bottom chambers, Aand B, having longitudinal openings, interior andApartly-perforated sidelugs cast integral With the Walls of the chambers, and the intermediatecastings, C C, each composed of a row of pipes having top and bottomflanges, substantially as described.

5. In a steam-radiator, the top and bottom chambers, A B, havingopenings a c and b b, interior and partly-perforated side lugs andperforated center lugs, said side and center lugs being cast integralwith the body of said chambers, substantially as described.

6. In a steam-radiator, the combination of the top chamber,A,providedwith longitudinal openings in its bottom, the steam-inlet pipe a', lugsc c3, partly-perforatedzcastings C C, nuts c2, the top plate, A, and thebottom chamber, B, provided With lugs c c3 and dischargingpipe.

In testimony that We claim the foregoing as our invention We have signedour names in presence of two subscribing Witnesses.
